Quick Verdict
AI summarizedSummarized with AI assistance from our human-researched product information, in-lab testing, objective sound measurements, and expert ratings.
The real choice here is performance and price versus support: the Sony CRE-C20 measured far ahead on speech clarity and costs about $1,700 less per pair, while the pricier Eargo 8 trails badly in our noise testing and only makes sense if its longer battery reserve and lifetime support team matter more to you than sound performance.
8
Choose the Eargo 8 if you want the longest battery life and case runtime in this pair and prioritize Eargo's lifetime customer support team, but be aware its 2.6/5 HearingTracker score and 0.3/5 speech-in-noise result sit well below average.
CRE-C20
Choose the Sony CRE-C20 if you want notably stronger measured speech clarity in quiet (4.7/5) and noise (3.2/5) after tuning, and you'd rather spend roughly $1,700 less for a pair.
What actually separates them
AI summarizedMeasured speech understanding
Lab measuredAfter tuning, the CRE-C20 scored 4.7/5 for speech in quiet and 3.2/5 for speech in noise, both well above the site-wide average, while the Eargo 8 measured 2.6/5 and just 0.3/5 on the same tests — a category-low result for noise performance.
Price for the pair
PriceThe CRE-C20 costs roughly $1,700 less than the Eargo 8, which is a large gap for two OTC devices in the same completely-in-canal form factor.
Overall expert rating and value score
Expert ratingThe CRE-C20 earned a 3.4/5 HearingTracker score and a 3.3/5 value rating versus the Eargo 8's 2.6/5 overall and 2.0/5 value score, reflecting our reviewer's view that the Eargo 8's price isn't matched by its lab performance.
Battery runtime
SpecThe Eargo 8 is rated for up to 16 hours per charge with a case offering up to two weeks of extra power, while the CRE-C20 runs up to 28 hours per charge with one additional day from its case — an advantage for the Sony on daily runtime despite Eargo's longer case reserve.

The Sony CRE-C20 is a discreet, over-the-counter hearing aid designed for individuals with mild to moderate hearing loss, featuring a compact size and rechargeable battery for up to 28 hours of use. While it offers a user-friendly setup and an Auto Sound Analyzer for enhanced speech clarity, it lacks Bluetooth streaming capabilities, which may be a consideration for users seeking more advanced connectivity options.

App Features

I found Eargo's app to be packed full of useful features like the Sound Match hearing assessment and automatic noise reduction controls. You have plenty of options for personalization though adjustments are not always reliable as Eargo relies on phone speaker commands instead of Bluetooth.
CRE-C20
3.0BELOW AVERAGE
Sony's Hearing Control app includes good features and allows your to further personalize CRE-C20 with their on-ear hearing assessment. One downside though is that the hearing aids and app communicate with sound cues from your phone. I find this method of wireless communication less reliable that Bluetooth, and it overall makes the pairing process more complicated.
Comfort

Comfort will vary by individuals depending on your tolerance to a deeper fitting hearing aid. Overall, I found them moderately comfortable through they can cause a tickling ear sensation due to their fit.

CRE-C20 are good comfortable once you find the best tip for your ears. They are not overly plugging though it can take some time to get used to having a hearing aid so deep in your ear canal.

Handling
8
3.0BELOW AVERAGE
Handling can be challenging with Eargo 8 due to the small size and reliance on tap controls. Furthermore, Eargo relies on acoustic indicators for wireless communication, which is less reliable than Bluetooth and caused me several problems.
CRE-C20
4.0AVERAGE
CRE-C20's smaller size and method of wireless communication make it more difficult to manage than many other hearing aids. However, Sony has improved upon the design as CRE-C20 now uses internal rechargeable batteries, as opposed to disposable ones. It is a unique offering with many pros but be sure to consider this against your needs and abilities.
Pro Support

Eargo is one of the first direct to consumer hearing aids, but support is unfortunately limited to to their Client Care team and personal hearing professionals. While Eargo claims they work alongside audiologists, it is not the same as direct professional hearing care.

Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.

This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.

Bottom Line
AI summarizedThe Verdict
The data here points strongly toward the Sony CRE-C20: it beat the Eargo 8 on every measured speech metric, carries a higher overall HearingTracker score (3.4 vs 2.6) and value rating (3.3 vs 2.0), and costs roughly $1,700 less per pair.
The Eargo 8's case only closes if you specifically need its longer battery reserve or its lifetime support team, since its 0.3/5 speech-in-noise score and 2.0/5 value rating are hard to justify at its price.
Which is right for you?
Neither device streams Bluetooth audio, so don't buy either expecting music or hands-free calling — that capability is absent from both. If sound performance in real-world noisy settings is your priority, the CRE-C20's tuned lab results make it the more defensible pick in this pair.
Before you buy
AI summarizedUse the return window to test in noise
Both are OTC purchases you can return, so wear each in a genuinely noisy room during the trial period — the CRE-C20's 3.2/5 lab score for speech in noise suggests it should perform far better there than the Eargo 8's 0.3/5.
Get a hearing test before buying either
Both devices are self-fit through in-app hearing assessments (Eargo's Sound Match, Sony's Auto Sound Analyzer), so confirm your loss is actually mild-to-moderate before choosing between them.
Weigh the $1,700 gap against Eargo's support
If ongoing help matters to you, factor in that Eargo offers lifetime phone/email/chat support while Sony's assistance is limited to phone and email — decide if that's worth the price difference.
Frequently Asked Questions
AI summarizedBased on lab and expert scoring, no — the CRE-C20 outperformed the Eargo 8 on speech in quiet, speech in noise, overall HearingTracker score, and value rating. The Eargo 8's higher price mainly buys longer battery life and Eargo's lifetime support team, not better measured sound performance.
No, neither device streams Bluetooth audio or supports hands-free calling. Both rely on acoustic or app-based communication with your phone instead of Bluetooth.
The Sony CRE-C20 runs up to 28 hours per charge versus the Eargo 8's 16 hours, though Eargo's charging case offers up to two weeks of extra power compared to the CRE-C20's one additional day.
Eargo offers lifetime phone, email, and chat support from its Client Care team, while Sony's CRE-C20 support is limited to phone and email assistance. Neither reaches the level of dedicated professional hearing care.
